$(object).css("border") doesn´t work in Firefox

[manuel.simon.steinberg@…]

I try to read the border css with the script in summary and everytime i get null as callback. i tried other options, e.g. "border-width" or "border-color", it doesn´t work in Firefox. In Opera it works!

From ​http://api.jquery.com/css/:

[Retrieval of] Shorthand CSS properties (e.g. margin, background, border) are not supported. For example, if you want to retrieve the rendered margin, use: $(elem).css('marginTop') and $(elem).css('marginRight'), and so on.

Use guaranteed-readable properties like "border-left-width", "border-bottom-color", etc.
